The chlorination of 1-hydroxy-3-phenyl-2(1H)-pyrazinone with phosphoryl chloride proceeded to 5-chloro-3-phenyl-2(H)-pyrazinone or 2,5-dichloro-3-phenylpyrazine on heating to elevated temperatures.To define the mechanism of the novel formation, reactions

The reactions of the monoxides of propylpyrazine and phenylpyrazine with phosphoryl chloride or acetic anhydride were investigated.Except in the case of the reaction of 2-propylpyrazine 1-oxide with acetic anhydride, chlorination or acetoxylation occurred
